DTW came over today to help me do front rotors and pads on my 70E, and well, DTW starts asking questions, and looking at things, and well

crap there is more work to be done.... Looks like my spindles are worn, possibly too much....
Does anyone have measurements for how much wear is too much on a front spindle? I just want to have something to compare to when I measure my spindles.
What do people think? I'd like comments on how this wear looks
Left side:
this is the side we were most concerned with... looks like the bearing started to chew up the spindle.
Right side:
The wear isn't as pronounced but you can still see it.
